I recently bought two bras and a pair of pocket leggings from Girlfriend Collective. They are a sustainability-focused brand and I was drawn by that and by the very wide size & racial diversity of their models, since I prefer to shop at places who showcase a lot of different types of people. Their size range -- and their models! -- go from xxs (22.5" waist) to 6xl (52" waist). The fabric is comfortable and pretty stretchy -- by strict measurements, I am right between XXL & XXXL, and the XXL leggings have plenty of room for me in it, and don't slide down or move around. I have gone for runs in them and also biked a bunch in them. The pockets are plenty large enough for my phone, and positioned so that my phone is comfortably against my thigh in a place where it will neither get sat on nor fall out if I'm biking (absolutely not true of all legging pockets).

Sadly, their bras do not fit me! I have too big a difference between bust measurement (46 1/2") and underbust measurement (33"). The bras I got are are size XXL (44-46" bust measurement) -- my usual compromise in soft bras like this is to buy the size below the bust measurement in the hopes the band will offer some support. In this case, there was neither any support nor enough fabric in the front to deal with my breasts. For comparison, my usual soft bra is the TomboyX Essentials Soft Bra in size XL, 41.5-43.5" bust/36-39" underbust -- it provides some support and has almost enough fabric for coverage, so it is an OK compromise size. Girlfriend Collective bras looked stretchy and accommodating on the website so I took a chance, but no dice -- it's just the wrong cut for me. The colors are lovely, the stitching is good-quality, and the fabric is soft and comfortable -- same as the leggings -- but I would recommend that anyone over a D-cup purchase with caution (I suspect it will depend on your exact breast shape and the exact bra), and over a G-cup definitely look elsewhere. A friend tried them at the same time I did and loves them! She wears hers as sports bras and says they're great.

I will definitely be going back for another pair of pocket leggings, and possibly some briefs. They have a wide variety of athletic wear and some comfy-looking loungey pieces, in a lot of colors. They will also recycle their own items once worn out, which I think is a nice touch! Prices range from about the mid-$30s to around $100ish for most items.
